Fecha de publicación: | 18-feb-2003 | Editor: | Sissa Medialab | Citación: | Journal of High Energy Physics 0302: 2 (2003) | Resumen: | We observe a relation between closed strings tachyons and one-loop instabilities in non-supersymmetric non-commutative gauge theories. In particular we analyze the spectra of type-IIB string theory on C3/ZN orbifold singularities and the non-commutative field theory that lives on D3 branes located at the singularity. We find a surprising correspondence between the existence or not of one-loop low-momentum instabilities in the noncommutative field theory and the existence or not of tachyons in the closed string twisted sectors. Moreover, the relevant piece of the non-commutative field theory effective action is suggestiv e of an exchange of closed string modes. This suggests that non-commutative field theories retain some information about the dynamics of the underlying string configuration. Finally, we also comment on a possible relation between closed string tachyon condensation and field theory tachyon condensation. | Descripción: | 21 pags. | Versión del editor: | https://doi.org/10.1088/1126-6708/2003/02/020 | URI: | http://hdl.handle.net/10261/249391 | DOI: | 10.1088/1126-6708/2003/02/020 | ISSN: | 1126-6708 | E-ISSN: | 1029-8479 |
